the gact that accounts can no be deleted is against Data Protection law

No it isn't, since you can easily delete any profile you created and change Email to a fake, non existing one. The data you crunched belongs to the project and needs to be maintained for the integrity of the science including its association to an individual account even if the account can no longer be traced back to the individual that created it.

the gact that accounts can no be deleted is against Data Protection law

Data Protection Laws dictate the ethics with which a company whom deals with your personally identifiable information, such as your Social Security Number if in the US, or any other type of confidential information must be handled.

Note that even if you close your bank account, which would have much of the personally identifiable information, the bank is required to keep certain records on file even if you close the account. Everywhere you go a trail is left behind.

SETI@Home, on the other hand, doesn't deal in such information. You create an account using a valid email address. You can optionally create a profile and enter any information you like, including false information. You can optionally delete this profile as well. The email address itself can be changed to anything at all, including an invalid one.

Since none of the information is verified, and none of it is personally identifiable unless the user puts it there (even then the user can remove it themselves), Data Protection Laws do not apply.

if you look at his computers you'll probably see the problem. He's got 4 and they are all the same machine. I'm betting he's messed with his linux OS trying to get BOINC to work on his own instead of asking for help. In a rich man's house there is no place to spit but his face.

Apparently, there are some people who --for whatever reason possible-- want all their personal info removed from project servers, not just have it hidden.

But OK, I've been emailing David about this. Whereas he wanted to deal with the problems if/when they emerged, I pointed out that the amount of people requiring this can probably be counted on the fingers of one hand. His last email back to me said he will disable the account deletion today.

My point of view on this is that it's got to be an admin job. It's OK to want to remove all your personal info and such from the project, but then make it an official request at an admin. One example I gave is what we do on the BOINC forums. Each month I make a list of the latest spam accounts, and send that to Dave, so he can remove them from the database. Not me, not Kathryn. We're only the hired help. So same thing with removal of accounts here: admin job. Jord

they'll probably have an internal trail to the work. Most likely they'll just relabel it as anonymous as so many users are running as such todayIn a rich man's house there is no place to spit but his face.
